Electric Double Layer Capacitors (EDLC)

Electric Double Layer Capacitors (EDLC), also known as super capacitors, are devices which store electrical energy in an electrostatic field. These devices are most commonly constructed from two carbon electrodes that are separated by an electrostatic dielectric material. The layers of energy are created through an electrostatic effect and the electrodes themselves act as both energy storage and current supply points. The PHB-5R0H305-R which is an EDLC, is a surface-mount flat-type super capacitor, designed specifically for automotive applications. It features an operating temperature range of -40°C to +85°C, low ESR of 35 mΩ.±20% at 120kHz 1Vrms, and a maximum voltage of 30V. The lifespan of the device is 5,000 hours and the dimensions of the PHB-5R0H305-R measure 7.3mm (Length) × 5.1mm (Width) × 3.9mm (Height).

Working Principle

The working principle behind the PHB-5R0H305-R EDLC is based on the electrostatic principles of the “double-layer effect”. This effect is created when two carbon faces of the EDLC face each other. The carbon faces consist of a negative and a positive electrode. As electrons flow between the two electrodes across the electrostatic field, a voltage is created. The electrostatic force of the EDLC causes electrons to form two layers of polarities. On the negative electrode, electrons build an electron layer near the surface of the material which is known as a ‘helium layer’. The helium layer attracts positively charged particles which then form a layer called the ion layer. This double layer of electron and ion layers forms a polarized electrical field which leads to the energy-storage effect. Therefore, when a potential difference is applied across the EDLC, electrons flow from the negative to the positive electrode. The two layers allow for a higher capacitance and rate of energy storage compared to a regular capacitor.

Application Field

Due to its high capacitance and rate of energy storage, the PHB-5R0H305-R is suitable for a range of applications including renewable energy storage, automotive industries, aerospace systems, and power line communication systems. The PHB-5R0H305-R is highly suitable for automotive applications due to its low ESR, high capacitance and rate of energy storage. It is capable of supporting spikes and bursts of voltage, making it an ideal component for automotive systems that require the reliable storage of energy. In terms of renewable energy storage, the PHB-5R0H305-R is ideal as it is capable of providing higher currents than regular electrolytic capacitors. This means that it can store energy at a much faster rate while still providing a reliable energy storage. The PHB-5R0H305-R is also suitable for use in aerospace systems due to its low ESR, high capacitance and low profile design. It is also capable of supporting high spikes of voltage, making it ideal for use in aerospace systems that require high energy storage. The EDLC is also used in power line communication systems, as it is capable of providing high energy bursts and current storage. This makes it ideal for communication systems that require bursts of energy to transmit data and information over long distances. Overall, the PHB-5R0H305-R EDLC is a highly versatile component that is suitable for a range of automotive, renewable energy storage, and aerospace applications. Its low ESR, high capacitance, and low-profile design make it ideal for use in these applications.
